Title: Liquid crystal display device
Inventor: TAKAHASHI KOJI
IPC: G02F1/133
Filed: 1989-04-17
Abstract: PURPOSE:To merely supply electric power at the start of use without being worried about a power supply sequence by closing a switch circuit and applying a voltage to a liquid crystal display element electrode only when both a power supply detecting circuit and a pulse detecting circuit detect objects of detection. CONSTITUTION:The power supply detecting circuit 1 detects the whether or not a power source 7 for logic circuits in a liquid crystal driving circuit 5 is turned on. Then the pulse detecting circuit 2 detects scanning pulses 8 and AC-generated pulses being supplied and an AND circuit 3 ANDs the outputs of the detecting circuits 1 and 2 so as to detect those pulses being supplied and the power source 7 for the logic circuits being turned on. Namely, only when the power source 7 for the logic circuits are on and the scanning pulses 8 and AC-generated pulses 9 are supplied, the switch circuit 4 is turned on to supply the electric power from a liquid crystal driving power source 10 to a liquid crystal driving circuit 5. Consequently, the order of the turning-on operation of the power source for the logic circuits and liquid crystal driving power source and the supply of the scanning pulses and AC-made pulses need not be controlled at the time of the power-on operation.

The gate valve driving gear 53, which drives a partitioning plate 51 for opening/closing a residual fuel gas duct 52, adjusts a position of the gate valve 51, so that a pressure of the fuel gas pressure detector 55 is generated equal to a pressure of the oxidizing gas pressure detector 56, to minimize leakage to the fuel duct 12 of oxidizing gas 4 from a sealing gasket 8 of a fuel cell 9. In this way, a fuel gas pressure in the fuel duct can be increased to a value suited for a pressure of the oxidizing gas flow passage.

Abstract: PURPOSE: Vane pump and flow rate control valve are integrally connected with each other, a partial pressure drop in the vane pump is effected upon the flow rate control valve and thereby a volume of pumping applied to such a fluid equipment as a power steering device etc. is decreased.  
     CONSTITUTION: When a number of rotation of the vane pump 3 is increased, the flow rate of suction into the pump changer arranged in a rear surface of the vane 7 is increased, a range of a partial pressure drop in the pressure chamber 22 which is generated near the intake port 24 is increased to act upon the opening of the orifice 32 and to decrease the pressure upstream of the orifice 32. Then the pressure downstream of the orifice 32 is also decreased, so that the pressure at the left side of the spool valve 27 communicating with the downstream of the orifice 32. Since the spool valve 27 increases a flow rate of hydraulic fluid to be returned to the tank 17 from the pressure chamber 22, a volume of liquid discharged from the port 30 to a fluid equipment is decreased.
